4 Claims. (Cl. 155-185) This invention relates to seat construction and has particularly to do with a method of and device for creating a bolster effect.

Vehicle seats of present day construction are many of them being provided with a so-called bolster effect which consists of tying down the top covering of the seat in a longitudinal line extending across the seat and relatively near the front edge. This causes the raising of a small cushion along the front edge of the seat and is designed to give comfort to the user by furnishing a support to the inner side of the knee joint.

It is an object of the present invention to provide an extremely simple manner of forming this bolster effect without radical departures from the usual seat construction. A further object is the provision of a bolster effect which is adjustable.

Another object of the invention is the provision of means for creating a bolster effect which may be readily tted into the rapid construction and assembly lines that are used today.

Other objects and features of the invention, having to do with details of construction and operation will be brought out in the following description and claims.

ln the drawings:

Fig. l is a perspective View of a seat showing generally the bolster effect.

Fig. 2 is a sectional view illustrating diagrammatically the spring construction showing the contour of the top seat cover and the means creating the bolster effect.

Fig. 3 is an illustration of the preferred form of creating a bolster effect.

Fig. 4 illustrates a longitudinal view of the seat covering at the point of bolster.

Fig. 5 illustrates a modified construction at the seat cover.

Fig. 6 illustrates a modified construction for fastening the bolster means to the frame.

Fig. 7 illustrates the adjustable feature of the bolster.

Fig. 8 is a detail of the clamp to be used.

Fig. 9 is a further modification of the bolster fastening at the seat cover.

Fig. 10 illustrates the manner in which the lower end of the bolster tapes may be fastened, and also a manner in which tufting may be accomplished, if desired.

In Fig. 2, a cushion frame is shown at and the coil springs 21 supported on the frame hold up the top seat cushion which consists of padding 22 and a seat covering material 23. The bolstered portion of the seat is represented at 24. The point of bolster is shown at 2S. This bolster effect may be created by a device shown in Figs. 3 and 4. First the seat cover 23 is seamed at 27 to form a roll 28. Before the sewing of seam 27, double tape loops 29 are spaced along the seat cover and sewn in to the roll 28. These tapes 29 are closed loops having at the lower end a stiff reinforcing head 30. This type of fastening device is shown and fully described in my Patent No. 2,192,161 of February 27, 1940.

ited States Patent 0 f j 2,391,682 Patented Aug. 6, 1957 rice After the sewing operation a wire 31 is passed through the seam and the tapes 29 are then drawn downwardly against the force of the springs and the cushioning matter 22. The heads 30 are anchored in holes in the frame. This is accomplished by turning the heads relative to the tape and passing them through a hole which has a diameter smaller than the length of the heads. The heads are then turned transversely and will be locked in position as shown in Fig. 3. If desired, a closed loop may be used and a relatively stiff rod 35 (see Fig. 6) passed through the lower ends of the loops 29a. Each end of the rod may then be anchored at the lower seat frame 36 by hog rings 37, after tension has been placed on the tapes.

The modied arrangement for fastening in the seat covering material is shown in Fig. 5. In this gure the seat material 23 is turned downwardly into a loop 38 and seamed at 39. The closed end of loops 29 are inserted through slits in the roll 38 and stapled or sewn in position. The wire 31 is then passed through as before and the same manner of fastening to the lower frame may be used.

A further modification is shown in Fig. 6 in which a downward loop is formed and this loop is provided at intervals along its length with perforations and eyelets pressed therein through which the tapes 29 may be passed. In Fig. 9 an open end of the loop would have to be passed through an then joined either to the fastening head 30 or to the other portion of the tape before the anchoring step.

In Figs. 7, 8 and l0 is represented a device for permitting adjustment of the bolster effect. In this device the rod type of anchoring means is used as shown, for example, in Fig. 6. At each end of the seat is provided a locking means 41 consisting of a member 42 fastened to the frame and a pivoting member 43. Each of these members has apertures adapted to register and receive an end of rod 3S. In creating the bolster effect with this device, the rod is fastened at intervals along its length to the tapes 29. One end is then fastened in one of the holes in the clamping means at one end of the seat (see Fig. 10). The other end is then pulled down into a corresponding position in the other clamping means and locked by means of a projection 44 on member 43 which clamps over member 42. The tension thus provided in the tapes 29 creates the bolster effect.

The same rod 35 and lock 41 may be used to effect a tufting of a cu;hion. In such case each of the tapes would be passed through the cushion to tufting buttons.

What I claim is:

l. A bolster seat which comprises a frame, spring means mounted thereon, a pad and top covering therefor supported by said means, a longitudinal loop sewed into said covering, a plurality of tape means having loops at one end sewed into said longitudinal loop, a rod means passing through said tapes and said loop, and means for fastening the tapes under tension to the frame to permanently force the padding at the front of the seat forwardly and upwardly and create a bolster eifect on said seat.

2. A bolster seat which comprises a frame, spring means mounted thereon, a top covering supported by said means, a longitudinal loop sewed into said covering, a plurality of tape means having loops at one end sewed into said longitudinal loop, a rod means passing through said tapes and said loop, and means for fastening the tapes under tension to the frame to create a bolster effect on said `seat, said means comprising loops formed at the depending ends of said tapes, a second rod means passing through said loops and extending along said frame, and means for adjustably fastening said second rod means to said frame in a position to exert downward tension on said tapes to create a bolster effect.

3. A bolster seat which comprises a frame, spring means mounted thereon, a top covering supported by said means, a longitudinal loop sewed into said covering, a plurality of tape means having loops at one end sewed into said longitudinal loop, a rod means passing through said tapes and said loop, and means for fastening the tapes under tension to the frame to create a bolster effect on said seat, said means comprising loops formed at the depending ends of said tapes, a second rod means passing through said loops and extending along said frame, and means for fastening said second rod means to said frame at points to exert tension on said tapes.

4'. A bolster seat which comprises a frame, spring means mounted thereon, a top covering supported by said means, a longitudinal loop formed in said'covering, a plurality of tape means, means for securing one end of each of said tape means at spaced intervals along said loop, the free depending ends being provided with a loop, a rod means passing through said loops and extending longitudinally of said frame, and clamp means for adjustably fastening said rod means to said frame in a position to exert downward tension on said tapes to create a bolster effect.
